SPECIFICATION forming part of LettersPatent No. 761,341, dated May'31, 1904.

Application filed February 4, 1904?. serial No. 191,959. (No model.)

Toatl whom it may concern:

- Beit known that I, HENRY B.TrJR NER, acitizen of the United States of America,and a resident of WashingtonCourt-House, county of Fayette, State of Ohio, have'in'vented certain new and useful Improvements in Rotary Engines, of which the following is a full and clear specification, reference being had to the accompanying drawings, in which- Figure 1 is a vertical sectional view'taken centrally through the engine; Fig. 2, a vertical sectional viewtaken at right angles to is provided with a continuous ring-like bore.

This casing or cylinder is constructed of two halves bolted together atv their outer edges by,

bolts 6. The piston c is circular in shape, so as to lit the bore of the cylinder, and is constructed in any suitable manner and projects radially from a disk d, to which it is rigidly attached in any suitable manner. The'disk dis keyed to the power-shafte and fits and works be' tween the inner edges of the casing-halves, suitable annular packages f being set in the adjacent faces of the casing-halves in order to prevent leakage of steam at these points.

zontally-disposed gate-box Q, in which is mounted on a vertical pivot h a rotary disk or gate 91, which extends across the cylinder bore and forms an abutment or head. Each of these gates is provided at its edge with a circular opening which is adapted to register with the bore of the cylinder and to permit f the piston to pass therethrough at certain in 'tervals. 'These disks are operated automatieally in any suitable manner. show consist of a cam j, fixed to the power-. shaft and adapted to actuate the rods in, which at their inner ends are provided with antifriction-rollers which bear upon the face of i the cam at diametrically opposite points. Each rod k is provided witha small piston Z,

The means I which works in a small cylinder m', mounted on the main cylinder and supplied with steam through a pipe 72 The outer end of each rod is, which works through the closed outer end of cylinder m,is pivotally connected tolthelink 0, which in turn is pivotally connected to a In operation it will be observed that the steam forces the piston to travel around the continuous cylinder, the gates or valves serving as heads or abutments. For instance, when the piston passes down through the opening in the right-hand gate said gate inumediately closes and steam is admitted under the same by means of the inlet-valve a. At the same instant the exhaust-valve q at the opposite side is caused to open, so that as the piston 0 moves around the steam in the compartment immediately ahead of it will pass out through said valve q. Then as piston 0 moves toward the left-hand gate or abutment the same will be caused to gradually open,

thereby letting a portion of the exhaust-steam into the upper half of the cylinder and permit it to pass out through the other exhaust-valve at the opposite side of the engine. When piston 0 passes through the left-hand gate, said gate immediately closes and the inlet-valve a" is opened, and as the piston travels toward the right-hand valve q the exhaust-steam ahead of it will be forced out through said Valve until the right-hand gate begins to open, whereupon a portion of the exhaust will pass into the lower part of the cylinder and out through the left-hand exhaust-valve, and so on. It will be observed that the gates or abut- Inents are opened gradually and closed suddenly. This gradual opening is accomplished by the rods and levers shown, and the sudden closing is obtained by the small steam-cylinders m, suitable means being provided to admit steam behind the small piston Z at the instant that the rollers on the rod k drop off the shoulder of the cam.

Any suitable mechanism may be employed to operate the valves 9 and 1. For instance, an eccentric may be keyed on the engine-shaft and connected to a rocker-arm attached to the main cylinder, which in turn drives a wristplate that oscillates on the cylinder through which the engine-shaft passes, the stems of the valve being connected to the wrist-plates by means of rods which are adjustable.

It will be observed that the engine takes steam twice in each revolution of the shaft, and it is obvious that any suitable automatic ent-off may be used, so as to permit the steam to work expansively.

It will be observed that this engine can be used for a great variety of purposes and may beset to run at any angle and in practically any position and also that it has amaximum of power, is very simple in all its parts, easy to repair, and has no dead-center. It will also be observed that it may be made to run from one revolution to an indefinite number of revolutions per minute and that it will be inexpensive to build.

It will be obvious from the foregoing that my in vention is not confined to the specific features of construction shown and described, and that, therefore, I reserve the right to vary the construction shown and described without departing from the spirit of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In combination with a ring-like cylinder, oscillating gates mounted therein and extending across the bore of said cylinder at diiferent points, means for slowly opening said gates, and steam-actuated means for quickly closing said gates, and inlet and exhaust valves adjacent to the gates, of a concentric power-shaft carrying a disk working through the inner wall of said ring-like cylinder and carrying a piston working in said bore.

2. In a rotary engine the combination, of a ring-like cylinder, oscillating gates mounted therein and extending across the bore of the said cylinder at different points, mechanicallyoperated means for slowly opening said gates, steam-actuated means for quickly closing said gates, a power-shaft carrying a disk working through the inner wall of said ring-like cylinder and carrying a piston working in said bore.

3. In a rotary engine the combination, of a ring-like cylinder, oscillating gates n'iounted therein, levers connectedto said gates, camactuated devices for moving said levers to open the gates, steam-actuated means to actuate said lever to close said gates, inlet and exhaust valves adjacent to the gates, a power-shaft carrying a disk working through the inner wall of said cylinder and carrying a piston working in said bore.

In testimony whereof I hereunto afiix my signature, in the presence of two witnesses, this 2d day of February, 1904.
